MAKE STABILISING RUMEN pH A PRIORITY TO MAINTAIN GRAZING BUTTERFATS
15 May 2015Milk producers looking to maintain butterfats following turnout are being urged to focus on stabilising rumen pH in order to boost the supply of milk fat-precursors to the udder. “Milk fat production is closely linked to the production of the volatile fatty acids (VFA) acetate and butyrate in the rumen, and they’re produced primarily by the microbes responsible for breaking down fibre,” explains Dr Derek McIlmoyle, AB Vista’s Technical Director for GB and Ireland. “Yet the efficiency of fibre breakdown is compromised any time rumen content drops below pH 5.8.
